ROTARY FIRE ESCAPE Filed June 15. 1928' v 15 one side of whichdes'cends and the other side shaft 13, parallel to shaft 10 and on each U l mma diet. It, Ease ABY nscann Application died June is, 1928. serial Ho. seam.

The object of my invention is to provide other end of the shaft is mounted a gear 9. a fire escape among other things, by which As a further part of my device, I have .the occupants of a burning building may mounted between the side frames 4, the addire 'ly escape and ma easily escape thru tional shaft 10 and on the outer end of shaft the windows of any of the floors of the build- I have mounted gear 11 and also crank ing, and also to provide a fire escape that handle 11', and which gear meshes with may be permanently attached to the outside gear 9. c of the roof of the building, and located upon As a further part of the device, also mounta track way or rails mounted to run from one. ed on shaft 10, I have a rotary overnor G; 10 side of the buildin to the other and a movmounted on shaft .5 I have ilso tween the U able carriage on w ich is constructed a turn side frames 4 the additional channeled pultable, whereby the ladder may be turned leys 12. from the front to the side of the building As a further art of my device, towards and providing means of an endless ladder, the opposite en of sills 2 I have mounted ascends at a controlled speed; also providing end of said shaft 13, I have mounted the means by which the speed may be regulated channeled pulleys 14; also as a further part for the ersons using it or by persons on top of my device and at the extreme outer end of of the uilding; also to provide an alarm the side sills 21 have mounted a further par- 0 sounding fire escape. allel shaft in the upper ends of the uprights w With these and other objects in view my 2', and on each end of said shaft 15 and beinvention consists in the following details of tween the side sills 2 I have mounted the construction and arrangement of parts as are channeled pulleys 16.

more clearly hereinafter described and As a further part of my device I have expointed out in the claims, reference being had tending around and over the channeled pul- 7G to the accompanying drawing, in which leys 12 the ladder side chalns 17, the said Fig. 1 is a plan view of my device. chains 17 extending from the upper surface Fig. 2 is a side view of my device. of channel pulleys 12 and down over the The same reference characters denote like channeled pulleys 16 and dropping to below H parts in each of the several. figures of the the channeled pulleys mentioned a distance 80 drawing. and then returning vertically u over the ex- In carrying out my invention I provide a tremely positioned pulleys 16, t ence back to frame structure A, which is formed on a base the under sideof and around over the chan of parallel side sills 2 and havin convenientneled pulleys 12. Mounted on the ulleys be- 85 ly spaced apart between the si s cross rods fore mentioned are the two side 0 ains men- .5 3 producing a rectangular frame structure. tioned, each in parallel position, as to each t the rear end of the frame structure A I other, and mounted between said parallel side have mounted on the side sills the vertical chains I have the ladder rungs 18, with reame supports 4, which forma rectangular cesses 19 in the sides of the pulley channels. frame work as shown in the drawing, or other Mounted upon the rungs in alinement with .9 form, in alinement with each other. .Mountthe center thereof, I have a. central cable 20, ed between .the raised side frames 4 I have which is fastened toeach, separate rung for a shaft 5, at right angles with the base sills the better and manipulation a dfgra'sping of of the frame A, and on shaft 5 is mounted persons using the escape. a gear 6; also between the 'side frames 4 I ,As a further part of m deviceand mounthave the additional shaft 7, parallel with ed upon the roof of the uilding, I have the shaft 5 and on one end of shaft 7 I have rail track B, composed of the parallel rails mounted a gear 8 which meshes with the op- 21 and extending parallel with h side of 1 posite gear 6; A crank handle 8' is provided the building to which the track is ad'acent. on the shaft 7 adjacent the gear 6 and an the Applicant elects to provide a single rail I track or a double rail track and to have said '22 traversin track curved at the corners of the roof surface to enable the. fire escape body to be moved and turned from facing one side of the buildin to another. IHave on said supporting rai 21a carriage C having wheels the rails. Y As a furt er part of my device I have mounted upon the carriage G a turn table disk E and upon this turn table disk E the base'sills and structure 2 of the fire escape body A may be mounted, and pivoted on pivot F.

As a further part of my device, mounted on the base sills 2 I have the side frame D and mounted therein I have the suspended bell bodies 23 and pivotall suspended in frame D, adjacent each bell ody 23, I have the pivotally mounted lever 24, the upper end of which is adapted to contact with the moving rungs 18 of the, ladder in opera-' I tion, and the hammer 25 at the lower end contacts with bell 23, as moves down or up.

As a further part of my device, mounted on spring grip hose nozzle 27, for carryin device to an upper part 0 lowering the same.

Having thus described my invention, what I claim as new and for which I desire Letthe chain ladder a hose or other I ters Patent is as follows leys therefor, a govermng mechamsm ment when in 'use, a

carriage,

1. In a rotary fire escape, with an endless ladder, of supporting pplor downward moveframe forsupporting said ladder with the ladder depending from one end thereof, a. carriage on' which the frame is pivotally mounted with the end of the frame from which the ladder depends, projecting beyond the carriage, and wheels for the carriage.

2. Ina fire escape,

controlling the ladder in its the combination with an endless ladder, of supporting pulleys therefor, a frame for supporting the ladder and pulleys, a carriage for supporting the frame, a turn table interposed between the frame and the carriage whereby the ladder ma be swung relative to the carriage, and rai s on which the carriage is movably mounted.

3. In a fire escape, the combination with a a turn table on said carriage, a frame supported by said turn table, pulleys arranged fore and aft of said frame, an endless ladder supported by said pulleys, means for operating the pulleys for raising and lowering the endless ladder, and governing greens for regulating the descent of the lad- 4. In a device of the class described, a carriage adapted to be moved to and fro on a a building or the like, a turn table mounted I have one or'more rungs of the ladder a 26, adapted to receive and hold a the combination frame and the ladder frame, operab e means the pulley shafts for controlling the spee of the endless ladder.

5. In a fire escape, the combination with a carriage, of rails on which the carriage is" movable to and fro, a turntable mounted on said carriage, a frame supported by-sai turntable, pulleys mounted on the frame, an endless ladder supported by the pulleys, and operating means for the pulleys for impartingnmovement to the endless ladder.

testimony whereof I have affixed my signature.
